I've heard a lot of stories on here about people inviting themselves, or assuming they get a plus one. How can I make it perfectly clear that no, you don't get a plus one.
FH and I decided that unless the couple's married/engaged, living together, or have been together 6 months or longer, they don't get a plus one. We're young, so most of our friends are single, and not allowing plus one's cuts our guest list down by almost 25%. But I also don't want to deal with the awkwardness of people assuming they get one.

To make this clear, address your invitations to EXACTLY who is invited (Mr. John Doe vs. The Doe Family). You can also add a line to your RSVP cards that indicates how many seats you have reserved in their honor. If RSVPs come in with additional guests, call the guest and let them know directly!
